Multi-story columns disappear when intersecting floor tiles

[GenuineSim]

Hello! I've been using 'moveObjects' to place columns through walls and on a single floor this hasn't been a problem. BUT when I attempt it with a multi-story column and it intersects a floor tile, it disappears when I move the view up to the second or third floor. If I remove the floor tile the column reappears, but then I have holes in the floor all along the wall where the columns have been placed :(

Does anyone know a way around this?

Thanks!
